If they are both the same age and both under the age of consent, it is not likely that the 16 year old male would face criminal charges, as long as, the sex was consensual. It would be difficult to rule that one gender has more culpability than the other or that one is a victim and the other is not if they are both the same age and both consenting to the act. It is more likely that there would be some type of remedy found in a juvenile court system or family court system for both 16 year olds. Both parents of the 16 year olds would have to be involved, or the court would have to emancipate both minors making them legal adults.
